Using DNS

Available in Classic and VPC

Before use

Q. What is DNS service?

• It translates domain names on the Internet to accessible IP addresses.
  
  For example, if you type http://www.example.com into your web browser, it needs to be translated into an IP address that matches the URL so that the system can access the server with it.

Q. What is NAVER Cloud Platform DNS?

• This service provides a DNS server, which is difficult for individuals to operate, in a cloud form so that users can easily and conveniently manage domain settings required for service operation. You can run your own DNS server without worrying about administrative aspects such as capacity, performance, and stability of DNS server.

If you want to register a new domain and use NAVER Cloud Platform DNS Service

1. Create a new domain in NAVER Cloud Platform DNS.

• Since the NAVER Cloud Platform DNS is not a service for domain registration, registration is required with the domain registration authority.

2. When you create a new domain in NAVER Cloud Platform DNS, you can check the name server information.

3. Register the name server of the domain newly registered from domain hosting services as the information of the name server provided by NAVER Cloud Platform DNS.

If you are using your own DNS service or another company’s and want to transfer it to NAVER Cloud Platform DNS

1. Create a domain to transfer in NAVER Cloud Platform DNS.

2. Replicate the resource record items of the domain you want to transfer to NAVER Cloud Platform DNS.

3. When you create the domain in NAVER Cloud Platform DNS, you can check the name server information.

4. Change the name server information of the active domain to the name server information provided from NAVER Cloud Platform DNS.
   (Changing the name server can take up to 48 hours.)

• You need to connect to the registration authority that registered your name server and change it through the 'Change Name Server Information'.
  • After transferring data from the existing operating domain, you must change it to the name server domain of the NAVER Cloud Platform DNS.

If you want to run sub domains in NAVER Cloud Platform DNS

(example.com -Active domain (parent domain), sub.example.com - Assuming a sub domain)

1. Create a new sub domain in NAVER Cloud Platform DNS.

2. Register the resource records required for the sub domain. If you already have a sub domain, which was serviced in an external DNS, register the same resource records.

3. You can check the name server information of the newly created sub domain from NAVER Cloud Platform DNS.

4. Register NS records for the sub domain (sub.example.com) in the parent domain (example.com). Register the name server information of the sub domain for NS record.
